DC Motor Repair Service

DC industrial motors are electromechanical devices designed to convert electrical energy into mechanical energy through the interaction of magnetic fields. They are commonly used in various types of machinery across industrial settings due to their reliability, controllability, and high starting torque. These motors can be found in a wide range of applications including:

  1. Conveyor Systems: DC motors are often employed in conveyor belts for material handling in industries such as manufacturing, logistics, and warehousing.
  2. Pumps and Compressors: They are used in pumps for water supply, wastewater treatment, and HVAC systems, as well as in compressors for air conditioning and refrigeration units.
  3. Industrial Fans: DC motors power fans used for ventilation, cooling systems, and air circulation in industrial facilities.
  4. Machine Tools: They drive various machine tools such as lathes, milling machines, and grinders in manufacturing processes.
  5. Automated Manufacturing Equipment: DC motors are integrated into robotic arms, CNC machines, and other automated equipment for precision control and movement.
  6. Printing Machinery: They are utilized in printing presses and other printing machinery for paper handling and printing processes.

DC industrial motors can fail due to various reasons, including:

  1. Overheating: Continuous operation at high loads can cause the motor to overheat, leading to insulation breakdown, winding damage, and eventual motor failure.
  2. Excessive Wear and Tear: Components such as brushes, bearings, and commutators can wear out over time due to friction, leading to reduced efficiency and eventual failure.
  3. Electrical Faults: Short circuits, insulation breakdown, or voltage spikes can damage the motor windings and other electrical components, resulting in malfunction or failure.
  4. Contamination: Dust, dirt, and moisture ingress can contaminate the motor internals, causing corrosion, insulation degradation, and eventual failure.
  5. Overloading: Operating the motor beyond its rated capacity can lead to mechanical stress, overheating, and premature failure of internal components.
  6. Improper Maintenance: Lack of regular maintenance such as lubrication, cleaning, and inspection can accelerate wear and tear, leading to premature failure of the motor.



Regular inspection, proper maintenance, and timely repair or replacement of worn-out components are essential to ensure the reliable operation and longevity of DC industrial motors in industrial machinery.

Due to the reasons listed above it is essential that DC motors are maintained on a regular basis.

Neu-servo offers a full repair service on all types of DC motors. We can also support your maintenance requirements on any DC drives that may require service or repair in our electronic repair shop. 

We offer all services 24/7.  

Our engineers will comprehensively assess the condition of your motors both Electrically and Mechanically. We use the latest cutting-edge Electrical testing technology to evaluate the condition of your motor. This equipment provides a complete and thorough Electrical test so that we can guarantee excellent working conditions following repair. 




We are also able to test all Tacho feedback packages and repair if necessary.

We also fully dismantle and inspect all mechanical parts to assess current condition. Following repair all mechanical parts are restored back to good working condition to ensure motor longevity.

This is especially important in DC motors due to the ongoing obsolescence issues relating to this type of technology.

All issues discovered are compiled in a report and quotation for you.

Following a thorough investigation, we will then fully service the unit back to new. This is a comprehensive Mechanical & Electrical refurb including commutator skim, overhaul of Brush gear assemblies and supply of new Brush gear, machining of any worn mechanical housings, seatings and shafts, and supply and fit of new bearings.

Finally, we provide full Field and Armature rewinds if required.

Motors will then be tested to nameplate specification to prove the repair.
